Sara Caldwell, DVM
Practice Owner
Dr. Sara Caldwell grew up in Atlanta Georgia with her mom and step-dad, one brother and a house full of pets. She is the owner of the practice and its primary veterinarian.  She always wanted to be a veterinarian since she was a little girl rehabilitating tiny birds that fell from their nest and putting pretend casts on her teddy bears.  She is thoroughly fulfilled by relieving the suffering of animals and is honored to be able to do so as a livelihood. She enjoys horses, specifically dressage, although she has evented, foxhunted and played polo.  Her favorite dog breeds tend to be brachycephalic (like pugs and bulldogs) but she has also owned and loved dachschunds, Danes, and heelers. She currently shares her home (and her heart!) with a pug, a Clyde cross horse, and her very sweet small child :)

Lead Veterinary Technician 
Our Mission Statement:
From a presentation given to a local business owners group in the summer of 2013 by Dr Caldwell
Katie recently moved to Oregon from Boulder, CO, and is thrilled to be part of the awesome team at Happy Valley Veterinary Hospital! She comes from a background in veterinary specialty & emergency facility management, and has spent the past few years working at a 24-hour veterinary clinic in Boulder. She is excited to learn more about role of general practice in helping to prevent serious health problems in pets, and enriching the lives of pets and their families.

An avid pet lover and rescuer, Katie has 4 
rescue kitties, one of which only has 3 legs and 3 teeth, and is the sweetest cat you’ll ever meet. Even though Katie holds a degree in English Literature, she has found her passion in veterinary medicine, and 
loves the joy and companionship animals bring to their families. She can’t wait to meet you and your pet at your next appointment!
